TinyIB - A Lightweight and Efficient [Image Board](http://en.wikipedia.org/wiki/Imageboard) Script
====

**Got database? Get speed.**  Use [MySQL](http://mysql.com) or [SQLite](http://sqlite.org) for an efficient set-up able to handle high amounts of traffic.

**No database?  No problem.**  Store posts as text files for a portable set-up capable of running on virtually any PHP host.

**Not looking for an image board script?**  TinyIB is able to allow new threads without requiring an image, or even disallow images entirely.  See the [Text Board Mode](https://github.com/tslocum/TinyIB/wiki/Text-Board-Mode) wiki page for instructions.

For demos see the [TinyIB Installations](https://github.com/tslocum/TinyIB/wiki) page.

**Note to those who have recently upgraded:** Are you unable to create new posts?  Run the SQL on [this page](https://github.com/tslocum/TinyIB/wiki/NewSQLStructure) to finish the upgrade process.

Installing
------------

 1. Verify the following requirements are met:
    - [PHP](http://php.net) 4 or higher is installed.
    - [GD Image Processing Library](http://php.net/gd) is installed.
      - This library is installed by default on most hosts.
      - If you plan on disabling image uploads to use TinyIB as a text board only, this library is not required.
 2. CD to the directory you wish to install TinyIB.
 3. Run the command:
    - `git clone git://github.com/tslocum/TinyIB.git ./`
 4. Copy **settings.default.php** to **settings.php**
 5. Configure **settings.php**
    - To remove the play icon from .SWF/.WebM thumbnails, delete or rename **video_overlay.png**
    - To allow WebA/WebM upload:
      - Ensure your web host is running Linux.
      - Install [mediainfo](http://mediaarea.net/en/MediaInfo) and [ffmpegthumbnailer](https://code.google.com/p/ffmpegthumbnailer/).  On Ubuntu, run ``sudo apt-get install mediainfo ffmpegthumbnailer``.
      - Set ``TINYIB_WEBM`` to ``true``.
    - To require moderation before displaying posts:
      - Ensure your ``TINYIB_DBMODE`` is set to ``mysql``, ``mysqli``, or ``pdo``.
      - Set ``TINYIB_REQMOD`` to ``files`` to require moderation for posts with files attached.
      - Set ``TINYIB_REQMOD`` to ``all`` to require moderation for all posts.
      - Moderate posts by visiting the management panel.
    - When setting ``TINYIB_DBMODE`` to ``pdo``, note that PDO mode has been tested on **MySQL databases only**.  Theoretically it will work with any applicable driver, but this is not guaranteed.  If you use an alternative driver, please report back regarding how it works.
 6. [CHMOD](http://en.wikipedia.org/wiki/Chmod) write permissions to these directories:
    - ./ (the directory containing TinyIB)
    - ./src/
    - ./thumb/
    - ./res/
    - ./inc/flatfile/ (only if you use the ``flatfile`` database mode)
 7. Navigate your browser to **imgboard.php** and the following will take place:
    - The database structure will be created.
    - Directories will be verified to be writable.
    - The file **index.html** will be created containing the new image board.

Moderating
------------

 1. If you are not logged in already, log in to the management panel by clicking **[Manage]**.
 2. On the board, tick the checkbox next to the offending post.
 3. Scroll to the bottom of the page.
 4. Click **Delete** with the password field blank.
    - From this page you are able to delete the post and/or ban the author.

Updating
------------

 1. Obtain the latest release.
 	- If you installed via Git, run the following command in TinyIB's directory:
 	  - `git pull`
 	- Otherwise, [download](https://github.com/tslocum/TinyIB/archive/master.zip) and extract a zipped archive.
 2. Note which files were modified.
    - If **settings.default.php** was updated, migrate the changes to **settings.php**
      - Take care to not change the value of **TINYIB_TRIPSEED**, as it would result in different secure tripcodes.
    - If other files were updated, and you have made changes yourself:
      - Visit [GitHub](https://github.com/tslocum/TinyIB) and review the changes made in the update.
      - Ensure the update does not interfere with your changes.
 3. Visit [GitHub](https://github.com/tslocum/TinyIB/wiki/NewSQLStructure) and check for new SQL queries which may be required to complete the update.

Migrating
------------

TinyIB includes a database migration tool, which currently only supports migrating from flat file to MySQL.  While the migration is in progress, visitors will not be able to create or delete posts.

 1. Edit **settings.php**
    - Ensure ``TINYIB_DBMODE`` is still set to ``flatfile``.
    - Set ``TINYIB_DBMIGRATE`` to ``true``.
    - Configure all MySQL-related settings.
 2. Open the management panel.
 3. Click **Migrate Database**
 4. Click **Start the migration**
 5. If the migration was successful:
    - Edit **settings.php**
      - Set ``TINYIB_DBMODE`` to ``mysqli``.
      - Set ``TINYIB_DBMIGRATE`` to ``false``.
    - Click **Rebuild All** and ensure the board still looks the way it should.

If there was a warning about AUTO_INCREMENT not being updated, you'll need to update it manually via a more privileged MySQL user.  Run the following query for one or both of the tables, dependant of the warnings you were issued:

``ALTER TABLE (table name) AUTO_INCREMENT = (value to be set)``
